Popeza masana akuchulukirachulukira komanso kuwala kwadzuwa kwambiri, tikuyenda m'misewu, sikovuta kuzindikira kuti anthu ambiri amavala magalasi a photochromic kuposa kale.Magalasi omwe amaperekedwa ndi dokotala akhala akuchulukirachulukira m'makampani ogulitsa zovala zamaso m'zaka zaposachedwa, ndipo magalasi a Photochromic akadali okhazikika pakugulitsa chilimwe.Msika ndi kuvomereza kwa ogula magalasi a photochromic zimachokera kumayendedwe awo, chitetezo chopepuka, komanso zosowa zokhudzana ndi kuyendetsa galimoto.
Masiku ano, anthu ambiri akudziwa kuti kuwala kwa ultraviolet kungayambitse khungu.Zodzitetezera kudzuwa, zodzitetezera, zipewa za baseball, ngakhalenso zophimba kumanja za silika wa ayezi zakhala zinthu zofunika kwambiri popita kokayenda m’chilimwe.Kuwonongeka kwa kuwala kwa UV m'maso sikungawonekere mwachangu ngati khungu lopangidwa ndi khungu, koma pakapita nthawi, kuwonetseredwa mopitirira muyeso kungayambitse zotsatira zoopsa kwambiri.Matenda a maso monga ng'ala ndi kuwonongeka kwa macular okhudzana ndi ukalamba atsimikiziridwa kuti ali ndi maulalo achindunji kapena osalunjika ku mawonekedwe a UV.Pakadali pano, ogula aku China alibe lingaliro logwirizana la "nthawi yovala magalasi" potengera kuwala kwa dzuwa.Nthawi zambiri, chilengedwe chowunikira panja chimafuna kale chitetezo chopepuka, koma ogula ambiri amawona kuti "sichofunikira" ndikusankha kusavala.Potsutsana ndi izi, magalasi a photochromic, omwe amapereka kuwongolera masomphenya ndi chitetezo chopepuka popanda kufunikira kochotsa monga magalasi a dzuwa nthawi zonse m'malo osiyanasiyana, akuvomerezedwa pakati pa anthu ambiri.
Mfundo ya kusintha kwa mtundu mu magalasi a photochromic imachokera ku "photochromism."M'malo akunja, ma lens awa amadetsedwa kuti afanane ndi magalasi adzuwa ndikubwereranso kumveka bwino m'nyumba.Khalidwe limeneli limagwirizanitsidwa ndi chinthu chotchedwa silver halide.Panthawi yopanga, opanga ma lens amalowetsa maziko kapena filimu wosanjikiza magalasi ndi ma microcrystals a silver halide.Ikayatsidwa ndi kuwala kwamphamvu, halide yasiliva imawola kukhala ayoni asiliva ndi ma halide ayoni, kutengera kuwala kwa ultraviolet ndi kuwala kwina kowoneka.Kuwala kwa chilengedwe kukakhala mdima, ma ayoni asiliva ndi ma halide ma ion amalumikizananso kukhala siliva halide pansi pa kuchepetsedwa kwa copper oxide, zomwe zimapangitsa kuti mtundu wa mandala ukhale wopepuka mpaka utawonekeranso bwino.
Kusintha kwa mtundu mu magalasi a photochromic ndi chifukwa cha zinthu zingapo zosinthika, ndipo kuwala (kuphatikiza kuwala kowoneka ndi kuwala kwa ultraviolet) kumagwira ntchito yofunika kwambiri pakuchita izi.Mwachibadwa, mphamvu ya kusintha kwa mitundu imakhudzidwa ndi nyengo ndi nyengo, kotero sizimasunga nthawi zonse zotsatira zokhazikika komanso zokhazikika.
Nthawi zambiri, nyengo yadzuwa, mphamvu ya kuwala kwa ultraviolet imakhala yamphamvu, zomwe zimapangitsa kuti pakhale chithunzithunzi chambiri, ndipo magalasi amadetsedwa kwambiri.Mosiyana ndi zimenezi, pamasiku mitambo, kuwala kwa UV ndi kuwala kwa dzuwa kukakhala kofooka, magalasi amaoneka opepuka.Kuonjezera apo, kutentha kumakwera, mtundu wa magalasi a photochromic umachepa pang'onopang'ono.Mosiyana ndi zimenezi, pamene kutentha kwatsika, magalasiwo amadetsedwa pang’onopang’ono.Izi zili choncho chifukwa pa kutentha kwakukulu, ma ion a siliva ndi ma halide ions, omwe poyamba anawola, amachepetsedwa kubwerera ku halide ya siliva pansi pa mphamvu zambiri, kuwunikira mtundu wa lens.
Pankhani ya magalasi a photochromic, palinso mafunso odziwika komanso chidziwitso:
Kodi magalasi a Photochromic ali ndi mawonekedwe ocheperako / kumveka bwino poyerekeza ndi magalasi wamba?
Magalasi apamwamba kwambiri a photochromic amakhala opanda utoto pomwe sanatsegulidwe ndipo alibe ma transmittance ocheperako kuposa ma lens wamba.
Chifukwa chiyani magalasi a photochromic sasintha mtundu?
Kusowa kwa kusintha kwa mtundu mu magalasi a photochromic kumakhudzana ndi zinthu ziwiri: mikhalidwe yowunikira ndi Photochromic agent (silver halide).Ngati sasintha mtundu ngakhale mu kuwala kolimba ndi kuwala kwa UV, ndizotheka kuti photochromic agent yawonongeka.
Kodi kusintha kwa mitundu kwa magalasi a photochromic kudzaipiraipira pakapita nthawi?
Monga magalasi aliwonse okhazikika, magalasi a photochromic amakhalanso ndi moyo wautali.Ndi chisamaliro choyenera, nthawi zambiri amakhala zaka 2-3.
Chifukwa chiyani magalasi a photochromic amakhala akuda pakapita nthawi?
Ngati magalasi a photochromic adetsedwa pakapita nthawi ndipo sangathe kubwereranso ku mawonekedwe owonekera, ndichifukwa chakuti ma photochromic ake sangathe kubwerera momwe analili poyamba atasintha mtundu, zomwe zimapangitsa kuti tint yotsalira.Izi ndizofala kwambiri pamagalasi apamwamba kwambiri, pomwe magalasi abwino kwambiri a photochromic sangakhale ndi vutoli.
Chifukwa chiyani magalasi otuwa ali ofala kwambiri pamsika?
Magalasi otuwa amatha kuyamwa infrared ndi 98% ya kuwala kwa UV.Ubwino waukulu wa magalasi a imvi ndikuti sasintha mitundu yoyambirira ya zinthu, kuchepetsa mphamvu ya kuwala.Amayamwa kuwala molingana pamawonekedwe onse, kotero kuti zinthu zimawoneka zakuda koma popanda kupotoza kwambiri kwamitundu, zomwe zimapatsa mawonekedwe enieni komanso achilengedwe.Kuonjezera apo, imvi ndi mtundu wosalowerera, woyenera kwa aliyense, ndikupangitsa kuti ikhale yotchuka kwambiri pamsika.
